Hello All! My dad picked up this bike for me for $30 I thought it was a good deal but it needs new tires. He says these are very dry. I also need to replace the tires on my Aunt old free spirit that she's giving me. Figured I could use 2 bikes in NYC, should one get stolen. Can anyone here please tell me where to begin? Maybe I could order the tires online and take them to a very well reviewed bike shop in midtown or the west village. Here are the pictures of the bikes! sorry not too many of the free spirit.
